Wind Slayer was a free (with optional payments) 2D
side-scrolling MMO that was comparable to other side scrolling
MMORPGs such as MapleStory and Ghost Online in many ways. It was shutdown in
August, 2011.

As with many MMOs the game attempts to give players many ways
to interact with one another (friend lists, team or solo player
versus player fighting, trading, etc.). The game is not gory (as it
does not depict blood) and it has a word filter to try and make it
suitable for players of all ages.

Every new character starts off as the novice class until the
character reaches level 10. At this point players can choose from
one of six permanent class changes (job advancements): Warrior,
Monk, Archer, Rogue, Mage, or Priest. Each class has their own set
of skills and can later advance again (at level 30) to one of two
choices that vary depending on the class chosen at level 10. Each
set of classes uses a certain stat and usually a secondary or third
stat that helps distinguish them from other classes and builds.
